Comparison of methods of monitoring structure deformations based on tests of a column-plate slab

Autor: Damian Nykiel

Publikováno v: Budownictwo i Architektura, Vol 20, Iss 4 (2021)

This work includes a comparison of the methods of monitoring the deformations of a structure on the example of a flat plate slab test. Classic ESG (electrofusion strain gauges) and modern DFOS (distributed fiber optic sensors) were compared. During t
